0005 * `subid` = 1 TBPX </br>
0006 `layer` = 1..4 </br>
0007 `ladder` = 1..28 depending on the layer </br>
0008 `nRowsInDet` = 656 for `layer` = 1,2 </br>
0009 `nRowsInDet` = 1320 for `layer` = 3,4 </br>
0010 `nColsInDet` = 442 for `layer` = 1,2 </br>

0014 `side` = 1 (-z), 2 (+z) </br>
0015 `disk` = 1..12 (disk = 1..8 for TFPX; disk = 9..12 for TEPX) </br>
0016 `blade` = 1..4 TFPX </br>
0017 `blade` = 1..5 TEPX </br>
0018 NB: the variable named `blade` corresponds to a phase2 ring </br>
0019 `panel` = 1 (always?) </br>
0020 `nRowsInDet` = 656 for `blade` = 1,2 </br>
0021 `nRowsInDet` = 1320 for `blade` = 3,4,5 </br>
0022 `nColsInDet` = 442 for `blade` = 1,2 </br>
0023 `nColsInDet` = 442 for `blade` = 3,4,5
0024
0025 ### RECHIT
0026
0027 * Local position of the `SimHit` (ranges below are approx) </br>
0028 `hx` [-0.83,+0.83] cm for 1x2 modules </br>
0029 `hx` [-1.67,+1.67] cm for 2x2 modules </br>
0030 `hy` [-2.24,+2.24] cm
0031
0032 * ToF of the `SimHit` corrected for the time-to-det (added in CMSSW 10.5.X</br>
0033 `ht` in ns
0034
0035 * Charge and ADC </br>
0036 `q` = charge of `RecHit` in e </br>
0037 `DgCharge` = charge of a single pixel in ke </br>
0038 NB: to get the ADC count (integer): `DgCharge*1000./600`. or `DgCharge*1000./135.` </br>
0039 Check always the value in the pset, e.g. </br>
